Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Herstellung eines Taschenfederkerns gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a device for producing a pocket spring core according to the preamble of claim 1.
Aus der
Mittels einer gattungsgemäßen Vorrichtung hingegen werden Schraubenfedern für Taschenfederkerne hergestellt, wobei über eine Zuführeinrichtung Federdraht in eine Windestation gebracht wird, in der jeweils eine Schraubenfeder gewunden wird, die zylinderförmig, insbesondere aber tonnenförmig ausgebildet ist.By contrast, by means of a generic device, helical springs for pocket spring cores are produced, spring wire being brought into a wind station via a feed device, in each of which a helical spring is wound, which is cylindrical but in particular barrel-shaped.
Nach dem Winden der jeweiligen Schraubenfeder wird diese an einer Windung von dem Greifer des Greifarmes gefaßt und beispielsweise einer Wärmebehandlungsstation zugeführt, in der das durch das Winden veränderte Gefüge normalisiert wird, so daß die ursprünglichen Federeigenschaften des Federdrahtes wiederhergestellt werden.After winding of the respective helical spring this is taken on a turn of the gripper of the gripper arm and supplied, for example, a heat treatment station in which the structure altered by the winding is normalized, so that the original spring characteristics of the spring wire are restored.
Anschließend durchläuft die erwärmte Feder eine Kühlstrecke, bis sie in einer weiteren Bearbeitungsstation in eine im weitesten Sinne Gewebeumhüllung eingetascht wird, so daß eine Federreihe entsteht, die entweder der Länge oder der Breite des Federkerns entspricht.Subsequently, the heated spring passes through a cooling section until it is eingetascht in another processing station in a broad sense tissue wrapping, so that a spring row is formed, which corresponds to either the length or the width of the spring core.
Danach werden mehrere Federreihen zu dem besagten Federkern miteinander verbunden. Dies kann durch Verklammern oder Verkleben geschehen.Thereafter, a plurality of spring rows are connected to said spring core with each other. This can be done by stapling or gluing.
Um Federkerne mit unterschiedlichen Festigkeitszonen herzustellen, werden bislang auf separaten Vorrichtungen Schraubenfedern mit unterschiedlichen Drahtstärken hergestellt, die jeweils zu einer der beschriebenen Federreihen zusammengefaßt werden. Durch Verkleben solcher Federreihen zu Zonen und deren Verklebung widerrum mit Federreihen, deren Schraubenfedern andere Windungszahlen aufweisen, kann ein Federkern mit unterschiedlichen Festigkeitszonen hergestellt werden.In order to produce spring cores with different strength zones, coil springs with different wire thicknesses have been produced so far on separate devices, which are each combined into one of the spring rows described. By gluing such rows of spring to zones and their adhesion umrum with spring rows whose coil springs have different numbers of turns, a spring core can be made with different strength zones.
Allerdings ist diese Art der Herstellung äußerst aufwendig, da sie in vielen Arbeitsbereichen manuell erfolgen muß. Zum anderen sind die unterschiedlichen Zonen in ihrer einen Ausdehnung durch die Länge der Federreihen definiert, d.h., entweder durch die Gesamtlänge des Federkerns, oder dessen Gesamtbreite.However, this type of production is extremely complicated, since it must be done manually in many areas. On the other hand, the different zones are defined in their one extent by the length of the spring rows, i.e., either by the total length of the spring core, or its overall width.
Partielle Zonen, also solche, die sozusagen inselartig in dem Federkern vorgesehen sind, sind mit den bekannten Vorrichtungen nicht herstellbar.Partial zones, ie those which are provided, so to speak island-like in the spring core, can not be produced with the known devices.
Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung der gattungsgemäßen Art so auszubilden, daß eine einfachere und kostengünstigere Herstellung eines Federkerns mit unterschiedlichen Festigkeitszonen möglich ist und die Gestaltungsmöglichkeit der Zonen hinsichtlich ihrer Anordnung und Konfiguration innerhalb des Federkerns verbessert wird.The present invention is therefore based on the object, a device of the generic type in such a way that a simpler and more cost-effective production of a spring core with different strength zones is possible and the design possibility of the zones is improved in their arrangement and configuration within the spring core.
Diese Aufgabe wird durch eine Vorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist.This object is achieved by a device having the features of claim 1.
Durch diese konstruktive Ausbildung der Vorrichtung kann nun ein Federkern mit unterschiedlichen Festigkeitszonen hergestellt werden, ohne daß eine zweite Vorrichtung zum Einsatz kommen muß.As a result of this construction of the device, a spring core with different strength zones can now be produced without a second device having to be used.
Bei unterschiedlichen Windungsanzahlen der Schraubenfedern sind auch die räumlichen Anordnungen der Windungen verschieden, so daß der Greifer, der ja, wie erwähnt, die fertig gewundene Schraubenfeder an einer Windung faßt, entsprechend positioniert werden kann. Hierdurch wird gewährleistet, daß die Schraubenfeder zum Weitertransport in jedem Fall korrekt ergriffen wird.At different Windungsanzahlen the coil springs and the spatial arrangements of the windings are different, so that the gripper, which, as mentioned, the ready-wound coil spring grasps a turn, can be positioned accordingly. This ensures that the coil spring is correctly gripped for further transport in each case.
Anstelle der Verstellbarkeit des Greifarmes zu der Windestation, besteht auch die Möglichkeit, diese in ihrem Abstand zu dem dann feststehenden Greifarm zu verändern , wobei jedoch diese Möglichkeit konstruktiv aufwendiger ist als die den Greifarm in seinem Abstand zur Windestation zu verstellen.Instead of the adjustability of the gripper arm to the wind station, it is also possible to change them in their distance from the then fixed gripper arm, but this possibility is structurally complicated than to adjust the gripper arm in its distance to the wind station.
Die Verstellung des Greifarmes bzw. der Windestation kann mittels eines Stellmotors erfolgen, der rechnergesteuert betrieben sein kann, so daß durchaus nacheinander Schraubenfedern gefertigt werden können, die unterschiedliche Windungsanzahlen aufweisen, wobei die Länge der einzelnen Schraubenfedern, aus der sich die Höhe des Federkerns ergibt, unabhängig von deren Windungsanzahl, etwa gleich ist.The adjustment of the gripper arm or the Windestation can be done by means of a servomotor, which can be operated under computer control, so that quite successively coil springs can be manufactured, which have different numbers of turns, the length of the individual coil springs, which results in the height of the spring core, regardless of their number of turns, is about the same.
Eine solche Fertigung erlaubt die Herstellung eines Federkerns, bei dem, je nach Bedarf, beispielsweise Zonen unterschiedlicher Festigkeit in der Eingangs genannten inselartigen Konfiguration hergestellt werden können.Such manufacturing allows the production of a spring core, in which, for example, zones of different strength in the input mentioned island-like configuration can be produced as needed.
Damit ist auch eine Individuelle Fertigung möglich, die den Bedürfnissen eines einzelnen Benutzers Rechnung trägt.Thus, an individual production is possible, which takes into account the needs of a single user.
Des weiteren kann vorgesehen sein, daß der Windestation eine zweite Zuführeinrichtung zugeordnet ist, der ein gegenüber der ersten Zuführeinrichtung in seiner Dicke unterschiedlicher Draht zugeführt wird, wodurch eine Schraubenfeder herstellbar ist, die sich ebenfalls in ihrer Festigkeit gegenüber einer anderen unterscheidet. In Kombination mit verschiedenen Windungsanzahlen sind somit vielfältige Festigkeitsunterscheidungen der Zonen herstellbar. Aber auch Federkerne, die sich in ihrer Gesamtheit von anderen hinsichtlich ihrer Festigkeit unterscheiden, sind ohne nennenswerte Umrüstung der Vorrichtung, geschweige denn ohne eine zusätzliche Vorrichtung zu fertigen.Furthermore, it can be provided that the wind station is associated with a second feed device, which is supplied with respect to the first feeder in its thickness different wire, whereby a coil spring can be produced, which also differs in their strength over another. In combination with different number of turns thus diverse strength distinctions of the zones can be produced. But also spring cores, the are different in their entirety from others in terms of their strength, are without appreciable conversion of the device, let alone to manufacture without an additional device.
Dazu trägt ebenfalls eine weitere Ausbildung der Erfindung bei, wonach die Schraubenfedern mit unterschiedlichen Windungsrichtungen hergestellt werden. Hierzu ist neben einer veränderten Zuführrichtung des Drahtes auch eine veränderte Drehrichtung der Windestation erforderlich.A further embodiment of the invention also contributes to this, according to which the coil springs are produced with different winding directions. For this purpose, in addition to a changed feed direction of the wire, an altered direction of rotation of the wind station is required.
Durch eine Mischung der Federreihen, bei der abwechselnd oder nach bestimmten Anzahlen Federreihen miteinander verbunden werden, deren Schraubenfedern rechts oder links gewunden sind, wird ebenfalls eine höhere Festigkeit des Federkerns insgesamt erzielt, zumindest aber wird ein "Schwimmen" durch Querverschiebung der beiden Breitseiten des Federkerns weitgehend vermieden.By a mixture of spring rows, in which alternately or after certain numbers spring rows are interconnected, the coil springs are wound right or left, also a higher strength of the spring core is achieved in total, but at least a "swimming" by transverse displacement of the two broad sides of the spring core largely avoided.
Bei einem mit Hilfe einer erfindungsgemäßen Vorrichtung hergestellter Taschenfederkern mit unterschiedlichen Festigkeitszonen, der aus einer Mehrzahl miteinander verbundener Federreihen, die jeweils in nebeneinander liegenden Taschen einer textilen oder textilartigen Umhüllung eingesetzte aus Federdraht bestehende Schraubenfedern aufweist, ist die Anzahl der Windungen und/oder der Durchmesser des Drahtes und/oder die Windungsrichtung der Schraubenfedern partiell unterschiedlich.In one produced by means of a device according to the invention pocket spring core with different strength zones, which consists of a plurality of interconnected spring rows, each used in juxtaposed pockets of a textile or textile-like sheath consisting of spring wire coil springs, the number of turns and / or the diameter of the Wire and / or the winding direction of the coil springs partially different.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand der beigefügten Zeichnung beschrieben.An embodiment of the invention will be described below with reference to the accompanying drawings.
Die einzige Figur zeigt einen Teilausschnitt einer erfindungsgemäßen Vorrichtung in einer schematischen Draufsicht.The single FIGURE shows a partial section of a device according to the invention in a schematic plan view.
In der Figur ist eine Vorrichtung zur Herstellung eines Taschenfederkerns dargestellt, die eine Windestation 6 aufweist, mit der eine Schraubenfeder 1 herstellbar ist.In the figure, an apparatus for producing a pocket spring core is shown, which has a Windestation 6, with which a coil spring 1 can be produced.
Eine Vielzahl von Schraubenfedern 1 werden in jeweils nebeneinander liegende Taschen einer nicht dargestellten textilen oder textilartigen Umhüllung eingesetzt, wobei eine vorbestimmte Anzahl der in die Taschen eingefügten Schraubenfedern eine Federreihe ergeben, von denen mehrere zu einem Taschenfederkern miteinander verbunden werden.A plurality of coil springs 1 are used in each adjacent pockets of a textile or textile-like enclosure, not shown, wherein a predetermined number of inserted into the pockets coil springs result in a row of spring, several of which are connected to a pocket spring core.
Der Windestation 6 ist eine Zuführeinrichtung 7 zugeordnet, durch die der Windestation 6 ein Federdraht 8 zugeführt wird, aus dem die Schraubenfeder 1 gewunden wird.The wind station 6 is associated with a
Zum Transport der gewundenen Schraubenfeder 1 in eine nachgeordnete Wärmebehandlungseinrichtung 9 ist ein Greifarm 2 vorgesehen, der auf einer Schwenkachse 4, die über einen Drehantrieb 5 bewegbar ist, gelagert ist.For transporting the coiled coil spring 1 in a downstream
Der Greifarm 2 weist an seinem freien Ende einen Greifer 3 auf, mit dem die Schraubenfeder 1 an einer Windung erfaßt und gehalten wird, so daß sie nach Fertigstellung der Windestation 6 aus deren Bereich in die Wärmebehandlungseinrichtung 9 transportiert werden kann.The
Um Schraubenfedern 1 mit unterschiedlichen Anzahlen von Windungen herstellen und bearbeiten zu können, ist der Greifarm 2 auf der Schwenkachse 4 so verstellbar gelagert, daß der Abstand des Greifarmes 2 und mit ihm des Greifers 3 zu der Windestation 6 veränderbar ist.In order to produce and edit coil springs 1 with different numbers of turns, the
Da der Greifer 3 die Schraubenfeder 1 immer an einer Windung ergreift, die Windungen bei unterschiedlichen Anzahlen jedoch eine andere Lage bezogen auf den Greifarm 2 einnehmen, muß dieser entsprechend verstellt werden.Since the
Im dargestellten Ausführungsbeispiel ist die Anzahl der Windungen der strichpunktiert dargestellten Schraubenfeder 1 größer als die der in Volllinie gezeigten.In the illustrated embodiment, the number of turns of the dash-dotted coil spring 1 is greater than that shown in full line.
Entsprechend ist der Greifarm 2 , der dann die Schraubenfeder 1 mit größerer Windungsanzahl ergreift, ebenfalls strichpunktiert erkennbar.Accordingly, the
Die durch Pfeile angedeutete Verstellbarkeit des Greifarmes 2 kann durch einen nicht dargestellten Stellmotor erfolgen, der rechnergesteuert die Lage des Greifarmes 2 verändert, so daß die Anzahl der Windungen der Schraubenfeder 1 beliebig wählbar ist.The indicated by arrows adjustability of the
Eine Kopplung des Stellmotors zur Lageveränderung des Greifarmes 2 mit der Windestation 6 ist sinnvoll. Hierdurch besteht die Möglichkeit, während der laufenden Produktion, also ohne die Vorrichtung still zu setzen in ihren Windungsanzahlen unterschiedliche Schraubenfedern 1 problemlos herzustellen und zu einem Taschenfederkern zu verarbeiten.A coupling of the servomotor for changing the position of the gripping
